A METHOD FOR THREE-DIMENSIONAL FLOW ANALYSIS IN A ROTOR USING A HIGH SPEED DIGITAL COMPUTER

Abstract

The theory presented develops a method for the analysis of steady, inviscid, adiabatic flow through arbitrary rotors. A detailed analysis in a meridional plane is given, assuming axial symmetry. A simplified approach to the blade to blade solution is also presented. The merits of these theories are compared with other proposed methods. The inverse, or design, approach is considered, and found to be unnecessary. A numerical solution for incompressible flow is derived and applied to the flow solution in the impeller of a mixed flow compressor with backwards-bent blades of arbitrary shape. Meridional streamlines and relative velocity distributions are progressively calculated on a CDC 1604 computer, using FORTRAN program language. Data are measured from a detailed presentation of the blade shape in a meridional plane. Blade to blade relative velocity distributions are calcualted from the meridional plane analysis. It is concluded that the results completely define the flow and are sufficiently accurate for engineering applications.
